Embodiment 1

[0029] The formula of lubricating oil is as follows: the base oil is UHVI 6 and 500SN, accounting for 59.4% and 25.4% of the total weight respectively; the reinforcing agent is H9300 and H9310, accounting for 4.4% and 1.75% of the total weight respectively; the viscosity index improver is T614, It accounts for 8.0% of the total weight; the pour point depressant is T803B, accounting for 0.6% of the total weight; the antioxidant is PKB900, accounting for 0.3% of the total weight; 0.06% by weight; the composite antifoaming agent T921 accounts for 0.09% by weight (the above are all percentages by weight).

[0030] The preparation process is as follows: first add base oil to the container, then add reinforcing agent, viscosity index improver, pour point depressant, antioxidant, molybdenum salt and antifoaming agent, stir until evenly mixed.

Embodiment 2

[0032] The formula of lubricating oil is as follows: the base oil is UHVI 6 and 500SN, accounting for 61.27% and 24.01% of the total weight respectively; the new reinforcing agent is H9300 and H9310, accounting for 4.23% and 1.71% of the total weight respectively; the viscosity index improver is T614 , accounting for 7.8% of the total weight; the pour point depressant is T803B, accounting for 0.61% of the total weight; the antioxidant is PKB900, accounting for 0.3% of the total weight; 0.06% of the total weight; the composite antifoaming agent T921 accounts for 0.01% of the total weight (the above are all percentages by weight).

[0033] The preparation process is the same as in Example 1.

Embodiment 3

[0035] The formula of lubricating oil is as follows: the base oil is UHVI 6 and 500SN, accounting for 55.85% and 28.4% of the total weight respectively; the new reinforcing agent is H9300 and H9310, accounting for 4.82 and 1.78% of the total weight respectively; the viscosity index improver is T614, It accounts for 8.1% of the total weight; the pour point depressant is T803B, accounting for 0.66% of the total weight; the antioxidant is PKB900, accounting for 0.3% of the total weight; the molybdenum salt is molybdenum dialkyl disulfate formate, accounting for 0.07% of the total weight ; Composite antifoaming agent T921 accounts for 0.02% of the total weight (the above are all percentages by weight).

[0036] The preparation process is the same as in Example 1.

Abstract

The invention relates to an additive for lubricating oil. The additive comprises a reinforcing agent, a viscosity index improver, a pour point reducer, a composite antioxygen, molybdenum salt and anti-foaming agent. The invention further relates to the lubricating oil composed of base oil and the additive for the lubricating oil. The novel additive for the lubricating oil is obtained by compounding components which are low in cost and easy to obtain according to different components and different proportions. Various performance indexes of the lubricating oil added with the additive are evidently improved, especially lubricating effect of the lubricating oil can enhanced, the problem that viscosity of the lubricating oil is reduced during service is solved and the service life of the lubricating oil is prolonged.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a lubricating oil additive and long-lasting lubricating oil containing the lubricating oil additive. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles in my country has increased significantly. Automobile energy consumption and environmental protection issues have aroused great concern from the whole society. The fuel combustion efficiency and lubrication and wear conditions of the automobile engine under the service conditions have the most significant impact on the energy consumption and environmental protection of the automobile, and put forward higher requirements for the lubricating performance and long-term stability of the lubricating oil. Friction and wear is a ubiquitous natural phenomenon. Friction loses about one-third of the world's primary energy. Wear is one of the three most important forms of damage and f...
